The present invention relates to novel cyclohexanediones having herbicidal activity, to agrochemical compositions containing those cyclohexanediones, to the use thereof for controlling undesired plant growth and to processes for the preparation of the compounds of the invention. The invention also relates to novel intermediates and to processes for the preparation thereof.

Numerous substituted cyclohexane-1,3-diones having herbicidal activity are already known. These compounds are not always satisfactory in terms of strength of activity, duration of activity, selectivity and applicability. It has surprisingly been found that, in contrast to these known compounds, the novel cyclohexane-1,3-diones of the general formula I and I' have good herbicidal activity.

The invention relates to the novel cyclohexane-1,3-diones of formula I or I' ##STR2## in which R¹ and R² independently of one another are each hydrogen; halogen; nitro; cyano; C₁ -C₄ alkyl; C₁ -C₄ alkoxy; C₁ -C₄ alkyl--S(O)n-; COR⁸ ; C₁ -C₄ haloalkoxy; or C₁ -C₄ haloalkyl; R³, R⁴ and R⁵ independently of one another are each hydrogen; C₁ -C₄ alkyl; or phenyl or benzyl each unsubstituted or substituted by up to three identical or different substituents from halogen, nitro, cyano, C₁ -C₄ alkyl, C₁ -C₄ alkoxy, C₁ -C₄ alkyl-S(O)n--, C₁ -C₄ haloalkyl, C₁ -C₄ haloalkyl-S(O)_(n) -- and C₁ -C₄ haloalkoxy; R⁶ is hydrogen; C₁ -C₄ alkyl; C₁ -C₄ alkoxycarbonyl; or cyano; R⁷ is OH; or O.sup.⊖ M.sup.⊕ ; R⁸ is OH; C₁ -C₄ alkoxy; NH₂ ; C₁ -C₄ alkylamino; or di-C₁ -C₄ alkylamino; n is 0, 1 or 2; M.sup.⊕ is a cation equivalent of a metal ion or of an ammonium ion that is unsubstituted or substituted by up to three C₁ -C₄ alkyl, C₁ -C₄ hydroxyalkyl or C₁ -C₄ alkoxy-C₁ C₄ alkyl groups.

In view of their chemical structure, the compounds of formula I can be regarded as 1,3-cyclohexanediones acylated in the 2-position. Numerous tautomeric forms can be derived from this basic structure. The invention includes all tautomers.

The individual meanings of the substituents R¹ to R⁷, which are separated from each other by semi-colons, are to be regarded as sub-groups of those substituents. The invention includes also the definitions of compounds of formula I that can be obtained by deleting one or more of those subgroups.

The compounds of formula I and I' exist in an equilibrium of the two forms according to the following equation: ##STR3##

In the case of the hydroxy compounds (R⁷ =OH), apart from the three enol forms Ia, Ia"' and Ia', the triketo form Ia" may occur in accordance with the following tautomeric equilibrium: ##STR4## The invention includes all the tautomeric structures that can be derived from the basic structures I and I' and the salts thereof (R⁷ =O.sup.⊖ M.sup.⊕).

Furthermore, the compounds of formula I and I" may be asymmetrically substituted (especially by the radicals R³ to R⁶ in the cyclohexane system). The invention includes both the racemate and the enriched and optically pure forms of the respective stereoisomers.

The asymmetrically substituted compounds of formula I are generally obtained in the form of racemates in the processes described in this application, provided chiral educts are not used. The stereoisomers can thus be resolved according to methods that are known per se, such as, for example, by fractional crystallisation after salt formation with optically pure bases, acids or meal complexes, or by chromatographic processes on the basis of the physicochemical properties.

Both the racemate and the stereoisomeric forms are included in the present invention.

Attention is drawn to the compounds of formula I or I' ##STR5## in which the pyridinecarbonyl radical is bonded by way of the 2-position of the pyridine system.

Attention is drawn also to the compounds of formula I or I' ##STR6## in which the radicals R¹ and R² are bonded in the 3- and 5-positions of the pyridine system.

Compounds of formula I or I' ##STR7## in which the radicals R¹ and R² are bonded in the 3- and 5-positions of the pyridine ring and the pyridinecarbonyl system is bonded by way of the 2-position of the pyridine ring are preferred.

Especially preferred are the compounds of formula I or I' ##STR8## in which R¹ is hydrogen; halogen; nitro; cyano; C₁ -C₄ alkyl; C₁ -C₄ alkoxy; C₁ -C₄ alkyl-S(O)_(n) -; COR⁸ ; C₁ -C₄ haloalkoxy; or C₁ -C₄ haloalkyl; R² is hydrogen; halogen; nitro; cyano; C₁ -C₄ alkyl; C₁ -C₄ alkoxy; C₁ -C₄ haloalkoxy; C₁ -C₄ alkyl-S(O)_(n) --; or C₁ -C₄ haloalkyl; R³, R⁴ and R⁵ independently of one another are each hydrogen; C₁ -C₄ alkyl; or phenyl or benzyl each unsubstituted or substituted by up to three identical or different substituents from halogen, nitro, cyano, C₁ -C₄ alkyl, C₁ -C₄ alkoxy, C₁ -C₄ alkyl-S(O)_(n) --, C₁ -C₄ haloalkyl, C₁ -C₄ haloalkyl-S(O)_(n) -- and C₁ -C₄ haloalkoxy; R⁶ is hydrogen; C₁ -C₄ alkoxycarbonyl; or cyano; R⁷ is OH; or O.sup.⊖ M.sup. ⊕ ; R8 is OH; C₁ -C₄ alkoxy; NH₂ ; C₁ -C₄ alkylamino; or di-C₁ -C₄ alkylamino; n is 0, 1 or 2; M.sup.⊕ is a cation equivalent of an alkali metal ion, an alkaline earth metal ion or an ammonium ion; of a mono-C₁ -C₄ -alkylammonium ion; of a di-C₁ -C₄ alkylammonium ion; of a tri-C₁ -C₄ alkylammonium ion; or of a triethanolammonium ion.

Of the afore-mentioned compounds of formula I or I' within the scope of the broadest generic meaning, and also of the emphasised, preferred and especially preferred generic definitions, attention is drawn in each case especially to the sub-groups mentioned below:

(a) Compounds of formula I or I' in which at least one of the radicals R³ to R⁶ is hydrogen,

(b) Compounds of formula I or I' in which at least two of the radicals R³ to R⁶ are hydrogen,

(i) Compounds of formula I or I' in which R² is hydrogen, chlorine, nitro, methylthio, methylsulfinyl, methylsulfonyl, methyl, fluorine, trifluoromethyl or trichloromethyl.

Attention is drawn especially to combinations of the sub-groups (a) to (e) with (h) and (i) both in the form of the free acid (group f)) and in the form of salts (group g)).

Especially preferred are compounds of formula I or I' in which R¹ is hydrogen; fluorine; chlorine; bromine; nitro; cyano; methyl; trifluoromethyl; trichloromethyl; methoxy; methylthio; methylsulfinyl; methylsulfonyl; carboxy; carbamoyl; methoxycarbonyl; or ethoxycarbonyl; R² is hydrogen; fluorine; chlorine; nitro; trifluoromethyl; trichloromethyl; methylthio; methylsulfinyl; or methylsulfonyl; R³ is hydrogen; C₁ -C₃ alkyl; phenyl; benzyl; or chlorophenyl; R⁴ is hydrogen; or methyl; R⁵ is hydrogen; or methyl; R⁶ is hydrogen; cyano; methyl; or C₁ -C₂ alkoxycarbonyl; R⁷ is OH; or O.sup.⊖ M.sup.⊕ ; is a cation equivalent of a sodium, lithium, calcium, trimethylammonium or triethanolammonium ion.

The following may be mentioned as individual compounds: 2-(3-chloro-5-trifluoromethylpyridin-2-ylcarbonyl) -cyclohex-1-en-1-ol-3-one and 2-(3-chloro-5-methylsulfonylpyridin-2-ylcarbonyl)-cyclohex-1-en-1-ol-3-one.

The compounds of formula Ia or Ia' in which the radicals R¹ to R⁶ are as defined hereinbefore and R⁷ is OH can be prepared by

(a) reacting a cyclohexanedione of formula II, in which the radicals R³ to R⁶ are as defined hereinbefore, with a pyridine of formula III, in which R¹ and R² are as defined hereinbefore and X is halogen, preferably chlorine or bromine or the radical ##STR9## and R⁸ is C₁ -C₄ alkyl, phenyl or benzyl, in the presence of a base ##STR10## (b) thermal rearrangement of an ester of formula IV or IV' in which the radicals R¹ to R⁶ are as defined hereinbefore ##STR11## preferably in the presence of cyanide.

The salts of formula Ib and Ib' in which the radicals R¹ to R⁶ are as defined hereinbefore and R⁷ is O.sup.⊖ M.sup.⊕ can be prepared by

(c) reacting a cyclohexanedione Ia or Ia' in which R¹ to R⁶ are as defined hereinbefore and R⁷ is OH with a base V in which B is OH.sup.⊖ M.sup.⊕, M.sup.⊕ being as defined hereinbefore ##STR12##

The esters of formula IV and IV' are valuable intermediates for the preparation of the herbicidal end products Ia and Ia' respectively according to process variant (b). The invention thus also relates to the novel esters Iv and IV'. The esters IV and IV' can, however, also be formed as by-products in the acylation according to process variant (a).

(d) Furthermore, the compounds of formula Ic or Ic' in which one or more of the radicals R¹ to R⁶ is (are) C₁ -C₄ alkyl-S(O)_(n) --, n representing 1 or 2, and the remaining radicals are as defined hereinbefore, can be prepared by oxidising a thioether of formula Id or Id', wherein the radical from the group R¹ to R⁶ that is to be oxidised is C₁ -C₄ alkyl-S(O)_(n) --with n representing 0, and the remaining radicals are as defined hereinbefore. ##STR13##

Such oxidations are familiar to the person skilled in the art (for example Methodicum Chimicum, Ed. F. Korte, 9. Thieme Verlag Stuttgart 1976, vol. 7, pages 696-698 and the literature sources mentioned there for oxidation to sulfenes, and vol. 7, pages 751-755 and the literature mentioned there for oxidation to sulfones).

Oxidation with H₂ O₂ and with per acids, especially with 3-chloroperbenzoic acid, is preferred.

By appropriate selection of bases, solvents and other reaction parameters, such as temperature, concentration etc., the O-acylation may become the main reaction in accordance with the following scheme: ##STR14##

In the C-acylation according to process variant (a) it has proved advantageous to carry out the reaction in the presence of small amounts of cyanide. A low cyanide concentration can be ensured, for example, by the addition of acetone cyanohydrin.

The rearrangement of the esters IV and IV' can also advantageously be carried out under the action of cyanide ions and in the presence of a base.

Although the synthesis of the compounds of formula Ia and Ia' outlined as reaction (a) describes a process by which in principle all compounds included within the scope of formula Ia and Ia' can be produced, for reasons concerning economy and industrial scale production it may be appropriate to convert certain compounds of formula Ia and Ia' into other derivatives included within the scope of formula I and I'. Examples of such conversions, apart from reaction (c) and (d), are, for example, processes in which R⁶ represents an ester, halogen or cyano radical. These radicals can be converted analogously to the reactions illustrated hereinafter in Scheme 1 (IIa→IIb, IIc or IId) also even at the stage of compounds of formula I. Such derivatisation reactions are familiar to the person skilled in the art.

The above reactions are advantageously carried out in a solvent that is inert with respect to the reactions. Suitable inert solvents are hydrocarbons, such as benzene, toluene or xylene; ethers, such as diethyl ether, methyl isopropyl ether, glyme, diglyme; cyclic ethers, such as tetrahydrofuran and dioxane; ketones, such as acetone, methyl ethyl ketone; amides, such as dimethylformamide, N-methylpyrrolidone; sulfoxides, such as dimethyl sulfoxide; or chlorinated hydrocarbons, such as dichloromethane, trichloromethane, tetrachloromethane or tetrachloroethane, alcohols, such as methanol, ethanol, isopropanol, propanol, butanol etc..

In some cases it is also advantageous to use mixtures of solvents in the form of organic solvents in admixture with water.

The reaction temperature can be varied within wide limits. Suitable reaction temperatures range, for example, from -20° C. to the reflux temperature of the reaction mixture. The reaction is preferably carried out at a temperature of from 0° C. to 100° C.

In the case of reactions (a) and (b) a base is advantageously added. Suitable bases are, inter alia, sodium, potassium and calcium hydroxide, alkali metal and alkaline earth metal carbonates, amines, such as, for example triethylamine, or heterocycles, such as pyridine, 4-dimethylaminopyridine, DABCO and also alkali metal hydrides.

Reactions (a) and (b) can also advantageously be carried out under phase transfer conditions in two-phase systems. Such reactions are familiar to the person skilled in the art (for example described in Dehmlow and Dehmlow, Phase Transfer Catalysis, Verlag Chemie, Weinheim 1983; W. E. Keller, Phase Transfer Reactions Vol. 1 and Vol. 2, G. Thieme Verlag, Stuttgart 1986, 1987).

The cyclohexanediones of formula II are either known or can be prepared analogously to processes known in the literature.

The following malonic ester synthesis is a general method of obtaining the cyclohexanediones II in which first of all, in accordance with the scheme below, the specifically substituted cyclohexanediones IIa, IIb or IIc can be produced from an aldehyde or ketone VI and acetone: ##STR15##

The compounds of formula IIc in which the radicals R³ to R⁵ are as defined hereinbefore and R⁶ is cyano can be prepared in a modification of reaction scheme 1 by Michael addition of cyanoacetic acid ester XIII, in which R⁵ is as defined hereinbefore and R' is C₁ -C₄ alkyl, to the ketone VIII, in which R³ and R⁴ are as defined hereinbefore. ##STR16##

Of the pyridinecarboxylic acid derivatives III, it is especially the acid chlorides that are preferred.

The pyridine-2-carboxylic acid chloride IIIa may advantageously be prepared by a Pd-catalysed carbonylation reaction in accordance with the following reaction scheme 3: ##STR17##

In the above scheme, Hal is halogen (especially chlorine); R' is C₁ -C₄ alkyl and Pd-Cat is preferably PdCl₂ (TPP)₂ a triphenylphosphine complex of palladium.

The picolinic acid derivatives XI, IIIa and XIV mentioned in scheme 3 are valuable intermediates for the synthesis of the cyclohexanediones I of the invention. Most of these compounds are novel.

The invention thus also relates to the novel picolinic acid derivatives of formula XV ##STR18## in which Y is OH; C₁ -C₄ alkoxy; or halogen; and R¹ and R² independently of one another are each halogen; nitro; cyano; C₁ -C₄ haloalkyl; C₁ -C₄ alkyl; C₁ -C₄ alkoxy; or C₁ -C₄ alkyl-S(O)_(n) --; n is 0; 1; or 2; with the proviso that when Y is chlorine and the radical R¹ is bonded in position 3 and the radical R² is bonded in position 5, R¹ and R² are not simultaneously chlorine or simultaneously methyl, or when R¹ is nitro R² is not methyl.

Preferred are picolinic acid derivatives of formula XV' ##STR19## in which Y is OH; C₁ -C₄ alkoxy; or halogen; and R¹ and R² independently of one another are each halogen; nitro; cyano; C₁ -C₄ haloalkyl; C₁ -C₄ alkyl; C₁ -C₄ alkoxy; or C₁ -C₄ alkyl-S(O)_(n) --; and n is 0; 1; or 2; with the proviso that when Y is chlorine, R¹ and R² are not simultaneously chlorine or simultaneously methyl, or R¹ nitro and R methyl.

Especially preferred are the compounds of formula XV' in which Y is OH; C₁ -C₄ alkoxy; or halogen; R¹ is hydrogen; and R² is C₁ -C₄ alkoxy, C₁ -C₄ haloalkyl; or cyano.

Also especially preferred are compounds of formula XV' in which Y is OH; C₁ -C₄ alkoxy; or halogen; R¹ is C₁ -C₄ alkoxy; C₁ -C₄ haloalkyl; or cyano; and R² is hydrogen.

Of the compounds of formula XV, and the compounds XV' mentioned as preferred and especially preferred, attention is drawn to the acid chlorides, that is to say those compounds in which Y is chlorine.

The compounds of formula I are highly active ingredients for plants that at suitable rates of application are excellently suitable as selective herbicides for controlling weeds in crops of useful plants. That is to say, at such rates of application the active ingredients of formula I are distinguished by a good selective herbicidal property against weeds. In particular, cereals, such as rye, barley, oats, wheat and maize, but also other crop plants, such as sorghum, rice, cotton, sugar cane or soybeans or also permanent crops (such as, for example, vines or plantations) remain virtually undamaged at low rates of application. At increased rates of application the growth of the crop plants is influenced only to a small extent. If the rates of application are very high, the substances of formula I have total herbicidal properties. The rates of application are generally from 0.001 to 4 kg. preferably from 0.005 to 2 kg of active substance per hectare.

At high rates of application the compounds of formula I can also be used as total herbicides. They are especially suitable for controlling weeds on paths, in public areas, on railway tracks or in other areas in which a total kill of the plants growing there is desired.

The selective herbicidal activity of the compounds of the invention is observed both in pre-emergence and post-emergence application. These compounds can therefore be used with equal success pre- or post-emergence in selective weed control.

Advantageously, the compounds or compositions of the invention can be applied also to the propagation material of the crop plant. Seed dressing, especially, may be mentioned here. Propagation material is seeds, plantlets or other parts of the plant from which the crop plants can be reared. The invention also relates to the propagation material treated with an effective amount of a compound of formula I.

The invention relates also to herbicidal compositions that contain a novel compound of formula I, and to methods for pre-and post-emergence weed control.

The compounds of formula I are used in unmodified form or, preferably, in the form of compositions together with the adjuvants conventionally employed in the art of formulation, and are therefore formulated in known manner e.g. into emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations in e.g. polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.

The formulations, i.e. the compositions, preparations or mixtures containing the compound (active ingredient) of formula I and, where appropriate, a solid or liquid adjuvant or extender, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredients with extenders, e.g. solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).

Suitable solvents or extenders are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms, e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols and their ethers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl or monoethyl ether, ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, as well as vegetable oils or epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil; or water.

The solid carriers used e.g. for dusts and dispersible powders are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are, for example, calcite or sand. In addition, a great number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite or pulverised plant residues.

Depending on the nature of the compound of formula I to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term "surfactants" will also be understood as comprising mixtures of surfactants.

Both so-called water-soluble soaps and also water-soluble synthetic surface-active compounds are suitable anionic surfactants.

Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C₁₀ -C₂₂), e.g. the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures which can be obtained e.g. from coconut oil or tallow oil. Mention may also be made of fatty acid methyltaurin salts.

More frequently, however, so-called synthetic surfactants are used, especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.

The fatty sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and contain a C₈ -C₂₂ alkyl radical which also includes the alkyl moiety of acyl radicals, e.g. the sodium or calcium salt of lignosulfonic acid, of dodecylsulfate or of a mixture of fatty alcohol sulfates obtained from natural fatty acids.

These compounds also comprise the salts of sulfated and sulfonated fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty acid radical containing 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolamine salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid, or of a condensate of naphthalenesulfonic acid and formaldehyde.

Also suitable are corresponding phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 moles of ethylene oxide, or phospholipids.

Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 10 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.

Further suitable non-ionic surfactants are the water-soluble adducts of polyethylene oxide with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol containing 1 to 10 carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit.

Examples of non-ionic surfactants are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol.

Fatty acid esters of polyoxyethylene sorbitan, e.g. polyoxyethylene sorbitan trioleate, are also suitable non-ionic surfactants.

Cationic surfactants are preferably quaternary ammonium salts which contain, as N-substituent, at least one C₈ -C₄ alkyl radical and, as further substituents, unsubstituted or halogenated lower alkyl, benzyl or hydroxy-lower alkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, e.g. stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.

Surfactants customary in the art of formulation are described, inter alia, in the following publications: "1986 International Mc Cutcheon's Emulsifiers and Detergents", Glen Rock, N.J., USA, 1986; H. Stache "Tensid Taschenbuch", 2nd edition, C. Hanser Verlag, Munich/Vienna, 1981; M. and J. Ash. "Encyclopedia of Surfactants", Vol. I-III, Chemical Publishing Co., New York, 1980-1981.

The active ingredient preparations usually contain 0.1 to 95%, preferably 0.1 to 80%, of a compound of formula I, 1 to 99.9% of one or more solid or liquid adjuvants, and 0 to 25% of a surfactant.

Preferred formulations are composed especially as follows (throughout, percentages are by weight)

Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations. The formulations can be diluted to a concentration as low as 0.001% active ingredient.

The compositions may also contain further additives such as stabilisers, antifoams, viscosity regulators, binders, tackifiers and also fertilisers or other active ingredients for obtaining special effects.

The following Examples illustrate the invention.

B. Biological Examples Example B1 Pre-emergence herbicical action

In a greenhouse, immediately after sowing the test plants in seed trays the surface of the soil is treated with an aqueous dispersion of the test compound obtained from a 25% emulsifiable concentrate. Various rates of application of active ingredient/hectare are tested. The seed trays are kept in the greenhouse at 22°-25° C. and 50-70% relative humidity and the test is evaluated after 3 weeks.

The herbicidal action is assessed in comparison with an untreated control group using a nine-stage evaluation scale (1=total damage of the test plants, 9=no herbicidal action on the test plants).

Ratings of 1 to 4 (especially 1 to 3) indicate a good to very good herbicidal action. Ratings of 6 to 9 (especially 7 to 9) indicate a good tolerance (especially in the case of crop plants). The test results for compound No. 1.005 are compiled in Table 4.

Example B3 Herbicidal action in paddy

The water weeds Echinochloa crus galli and Monocharia vag. are sown in plastics beakers (60 cm² surface area, 500 ml volume). After sowing, the beakers are filled to the soil surface with water. 3 days after sowing, the water level is raised to slightly above (3-5 mm) the surface of the soil. Application is carried out 3 days after sowing by spraying an aqueous emulsion of the test substances onto the vessels at a rate of application of 60 to 250 g of active ingredient per hectare. The plant beakers are then placed in a greenhouse under optimum growth conditions for the rice weeds, i.e. at 25°-30° C. and high humidity. The tests are evaluated 3 weeks after the application. The compounds of Table 1 damage the weeds but not the rice.
